I am referring to this page:

https://www.instana.com/docs/setup_and_manage/host_agent/updates/#update-interval

Is there a way to pass mode and time from outside as environment variables or any other way beside logging into the pod and manually changing the files inside etc/instana/com.instana.agent.main.config.UpdateManager.cfg file?

To whoever removed his/her answer: It was a correct answer. I don't know why you deleted it. Anyhow, I am posting again in case someone stumbles here.

You can control frequency and time by using INSTANA_AGENT_UPDATES_FREQUENCY and INSTANA_AGENT_UPDATES_TIME environment variables.

Updating mode via env variable is still unknown at this point.

Look at this page for more info: https://www.instana.com/docs/setup_and_manage/host_agent/on/docker/#updates-and-version-pinning

Most agent settings that one may want to change quickly are available as environment variables, see https://www.instana.com/docs/setup_and_manage/host_agent/on/docker. For example, setting the mode via environment variable is supported as well with INSTANA_AGENT_MODE, see e.g., https://hub.docker.com/r/instana/agent. The valid values are:

  • APM: the default, the agent monitors everything
  • INFRASTRUCTURE: the agent will collect metrics and entities but not traces
  • OFF: agent runs but collects no telemetry
  • AWS: agent will collect data about AWS managed services in a region and an account, supported on EC2 and Fargate, and with some extra configurations, on hosts outside AWS

On Kubernetes, it is also of course possible to use a ConfigMap to override files in the agent container.

  • It would be nice to write the modes and a use case directly in your answer, in case the original link is not available. – h3ct0r Oct 17 '20 at 22:27
